During a battle between immortals and demons, the god Wangchuan fell in love with Shi'er, a goblin, and was thrown into the mortal world and suffered all kinds of human suffering. However, Shi'er was punished by being struck by five thunders every ten years and pierced by ten thousand swords every hundred years. However, she still did not give up looking for Wangchuan.
Three hundred years later, Shi'er found Wangchuan, but at this time, his name was Zhang Ceyi, and he was the eldest young master of Zhang Yuanwai's house. Shier wanted to help Ceyi return to his position as soon as possible, and then ended the world of mortals, but Ceyi couldn't let go of Shier, and the black snake demon Tianxie who wanted to marry Shier wanted to kill Ceyi. How would Shier face it?
